<p>
  Reports code that uses <code>==</code> or <code>!=</code> rather than <code>equals()</code> to test for object equality.
</p>
<p>
  Comparing objects using <code>==</code> or <code>!=</code> is often a bug,
  because it compares objects by identity instead of equality.
  Comparisons to <code>null</code> are not reported.
</p>
<p>
  Array, <code>String</code> and <code>Number</code> comparisons are reported by separate inspections.
</p>
<p><b>Example:</b></p>
<pre><code>  <b>if</b> (list1 == list2) {
    <b>return</b>;
  }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>  <b>if</b> (Objects.equals(list1, list2)) {
    <b>return</b>;
  }
</code></pre>
